Hello I've OTRS 2.4.7 with ITSM modules in it. It's running under a MS Win2k3. Everything's working smooth, been configuring ITSM Classes with no problem, except this one: I can run any predefined Stats but when I try to create a new one, the browser shows me the 500 Internal Server Error error. Looking at the error.log from apache i get: [Wed Aug 18 09:52:08 2010] [error] ERROR: OTRS-CGI-10 Perl: 5.10.0 OS: MSWin32 Time: Wed Aug 18 09:52:08 2010, referer: http://otrs.somedomain.com/otrs/index.pl?Action=AgentStats&Subaction=Overvie...
